Title: Semiconductor light emitting element
Inventor: TAKADA TOSHIHIRO
IPC: H01S5/12
Filed: 1986-10-31
Abstract: PURPOSE:To make it possible to add a photodetector for monitoring output light to a distribution feedback type semiconductor light emitting element as a body, by using the corrugation of the distribution feedback type semiconductor light emitting element, which has the corrugation in an active layer, as the secondary corrugation, and providing a slit in an outer region of the corrugation. CONSTITUTION:A slit 12 is formed at a point which is separated by about 100mum from the side of a high reflecting surface in parallel with the high reflecting surface by using a photolithography method so that the width of the slit is about 10 mum. The depth of the slit 12 is specified so as to reach a cap layer 4. One side (side of high reflecting surface) which is isolated by said slit is a light receiving part 14. The other side is a semiconductor light emitting element body. In the light receiving part 14, a positive electrode 1 is converted into a positive electrode 2 of the light receiving part 14. A contact layer 11 and the cap layer 4 are converted into p-type regions 3 of the light receiving part 14. Thus, the light receiving part 14 functions as a photodetector, which receiving leaking light having intensity proportional to the intensity of laser light.

Filed: 1992-09-30
Abstract: PURPOSE:To obtain an excellent heat efficiency by disposing a reflective member converging radiant heat of a heating lamp to the contact position of a fixing roller and a pressing roller on an outer periphery surface of the fixing roller. CONSTITUTION:Because the radiant heat of the heating lamp 15 is converged to the contact position of the rollers 11 and 12 by the reflective member 16, passing through a circular tube 14 of the fixing roller 11, toner 9 to be pressed onto printing paper 4 between these rollers 11 and 12 is melted and fixed onto the printing paper 4 by utilizing the radiant heat concentrated by the reflective member 16 and the heat transmitted from the rollers 11 and 12. That is, since the toner 9 on the printing paper 4 is heated by utilizing the radiant heat of the heating lamp 15 in the fixing device 10, it is unnecessitated that the fixing roller 11 is heated to a high temperature, the response property of the fixing action is satisfactory and the heating efficiency is improved. Furthermore, since an insulation member 17 is provided on the outer periphery part of the reflective member 16, the heat quantity of the fixing roller 11 is prevented from being discharged to the outside and the heat efficiency is improved.

Title: Abnormality detector for on-load tap changer
Inventor: IMAI MITSUO
IPC: H01F29/04
Filed: 1990-09-27
Abstract: PURPOSE:To detect the abnormality or a sign of abnormality of an on-load tap changer by specifying the abnormal spot by discriminating the abnormal spot by comparing a normal current pattern from a normal current pattern storing section with the output of a current sensor section in a switching pattern. CONSTITUTION:A switching pattern discriminating section 11 discriminates a switching pattern on the basis of an actuating signal from a storing section 10 and sends the information to a normal current pattern storing section 12. An abnormal spot discriminating section 13 compares a current pattern at the time of switching operation from the storing section 10 with the normal current pattern in a normal current pattern storing section 12 selected by means the switching pattern discriminating section 11. When the ratio (difference) between both patterns exceeds a prescribed set value, the section 11 discriminates that abnormality or a sign of abnormality exists and specifies the abnormal spot from the time zone during which the ratio (difference) exceeds the preset value. Therefore signal detection and handling can be performed easily and any abnormal spot can be surely discriminated.

Title: Precast concrete foundation
Inventor: NUNOMURA YUTAKA
IPC: E02D27/01
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To open holes easily at a construction site and obtain the foundation at a low cost by installing recesses with the outside face side covered with thin-walled parts, on the inside of a foundation beam part, and cutting off the thin-walled parts to form piping holes. SOLUTION: A precast concrete foundation for a projected corner is previously installed at a projected corner part, and each side length and diagonal dimension are adjusted. The precast concrete foundation 2 for a linear part is then installed between the foundations and jointed, and a large number of recesses 3, 3 are arranged with longitudinal spaces at the inner side face. At this time, the outer side faces of the foundations 2, 2 are covered with thin-walled parts 4, 4 so as to be flush with each other, and the corresponding thin-walled parts 4 at the time of passing piping are cut off into the same shape as the recesses 3 to open piping through-holes. The projected corner foundation and the linear part foundation 2 correspond only to a foundation beam part of inverted T- shape. As to a base part, a form is installed and concreted in site after the arrangement of reinforcements.  Work can therefore be performed easily compared to the case of boring the thick-walled foundation at the construction site.

Title: Semiconductor laser
Inventor: HIUGA SUSUMU
IPC: H01S5/00
Filed: 1984-12-14
Abstract: PURPOSE:To set the transverse mode of a semiconductor laser into a zero-order mode and to make its far field pattern into a single peak type by a method wherein the photo absorption layer in the lower direction of the face of the P-N junction having a plural light-emitting regions is provided with a distribution in its thickness in such a way as to have a distribution in its photo absorption factor in the lower direction of the P-N junction face. CONSTITUTION:An etching is performed on a blocking layer 5a between stripes 7 to provide a groove, the loss in this groove part is sufficiently lessened and the zero-order and primary transverse modes are made easy to be excited in the same degree. Moreover, as the distance between an active layer 3 and blocking layers 5 are close at the outside of the two-strip stripes 7, light is absorbed and the loss is large, the primary transverse mode having a large electric field strength is large in loss as a whole in the outside parts and becomes hardly to be excited. By this way, the zero-order transverse mode only can be excited, thereby enabling to obtain a good-quality laser beam, whose far field pattern is a single peak type and coupling property with fibers is good.
